ment in Plaster-Supports for Wall-Covering, of which the following is a full, clear, and exact description.

My invention relates to improvements in plaster supports such as are attached to the studding of a wall in lieu of lath, and to which a, body of plaster is afterward applied, although my improved plaster support. may be used in itself for a wall covering if desired, as it forms a much stronger surface than ordinary paper or other fabric.

The prime object of my invention, however, is to produce a cheap, perfectly flexible and exceedingly strong plaster support which can be rolled up and easily shipped, which can be readily applied to the studding of a wall or ceiling beams, and which will afford a good surfaceon which to plaster and will have sufiicient strength to maintain the plaster until the latter is set.

It is well understood in the trade that a paper surface is a most excellent material to which wet plaster may be applied, as the plaster enters the pores of the paper and anchors itself thereto. A diificulty has been found, however, in the fact that plaster when applied is saturated with water and aper or analogous fabric, becomes quic ly saturated, loses its tensile strength, and either breaks away while wet or else sags to such an extent that a good deal of extra plaster is necessary in the finishing coat or coats in order to make the surface level. To overcome this objection I have used a paper preferably laminated and provided with thin flexible cross strengthening strips as disclosed in my application for Letters Patent of the United States No. 572,088, filed July 15th, 1910.' l find that this strengthening of the fabric, which is preferably paper, is a great advantage and that it does not interfere with the rollin and shipping and .otherwise handling 0 the paper, but I find also that it is desirable to strengthen and stiffen the fabric between the transverse strengthening strips, so that there will be no tendenc to sag either transversely or longitudinal to the end that the paper may be kept perfectly flat after the wet plaster is applied. To bring about this result I have discovered that I can incorporate in the. body of the fabric which as wires can stated is preferably paper, longitudinal strands of fine material, and this material is preferably very fine wire. If the paper is laminated, the wire can be readily laid between these adjacent sheets, and so the paper .or other fabric will on its surface, appear like the ordinary roll of paper, but it will be extremely stron of these strands w ich correspond to the warp of woven goods,-while in theother 'direction the plaster supporting sheet will be strengthened .by the transverse strips above referred to and disclosed in my prior application above mentioned. All this will be made very clear from the description which follows. i

lengthwise by reason Reference is to be had to the accompanying drawings forming a part of this specification, in which similar reference characters indicate corresponding parts in all the views.

Figure 1 is a perspective view of a roll of material made in accordance with my invention. Fig. 2 is a front elevation showing the material as applied to the studding of a room, the studding being shown by dotted lines. Fig. 3 is a transverse section of a sheet of the material enlarged to bring out its structure, and Fig. 4 is a flat view of a strip of the material, the parts being broken away to disclose the location of the strands or wires.

The plaster sheet 10 is made preferably of laminated paper so that it can be rolled up readily as in Fig. 1, and of a width which will enable it to be applied readily to the studding of a room, a convenient width being such as to span the space of two ordinary studs as shown in Fig. 2. Obviously this width may be varied, however. As illustrated the sheet is made up of two layers of fabric 11 and 11, though more layers can be used if desired, and the sheet is strengthened by the transverse fiat strengthening strips 12, all ofwhich is as disclosed in -my prior application above named. The novel feature of this invention, however, lies inthe application to the fabric'of the longitudinal strands 14 which can be of any approved strengthening material,

but which are preferably in the form of metallic wires made very fine so asto be readily incorporated with the plaster supporting sheet 10, and it will be seen that fine be readily fed between the two sheets 11 and 11 as the latter are united by pressure, cement, or otherwise. When the sheet is complete, the wires are of course not shown as they will be hidden in the middle of the plaster sheet, but it will be seen that the sheet will be enormously strengthened in the direction of its length, and as it is also strengthened transversely by the strip 12, it will be'able when attached to the stud ding or ceiling beams, to form a perfect support for wet plaster and even for the plaster after it is \dried.

In carrying out my invention, the strands 14: can be applied in the most convenient ject of the wires 1s, as stated, to keep the paper taut and flat between the transverse strengthening strips until the wet plaster has set, and if the wires should rust out afterward it would not be material, as the plaster would be in its-flatlposition, and the paper when dry is sufliciently strong.

I claim A plaster support comprising a plurality of flexible sheets of paper united so as to form a single flexible sheet, longitudinal strands embedded between the paper layers,

and thin, fiat, transverse strengthening" strips spaced apart and firmly secured to the surface of the paper.
